Flicker assessment of low-to-medium frame-rate binary video halftones

Video display on devices with limited bit-depth capabilities requires conversion of the original (continuous-tone) video having a higher bit-depth to one having a lower bit-depth. Video halftoning refers to a process that attempts to perform this conversion such that the resulting halftone video is perceptually similar to the continuous-tone video. This quantization process, however, results in artifacts. A video halftoning algorithm can be assessed by quantifying the artifacts introduced by it. In this paper, we discuss an approach to assess flicker, a typical temporal artifact, in low-to-medium frame-rate binary video halftones produced from grayscale continuous-tone videos.
